Fantom [35]2 years ago
4 0

Answer:

Mass = 14.876 g

Explanation:

Given data:

Volume of gold = 0.77 cm³

Mass of gold = ?

Solution:

Density of gold from literature is 19.32 g/cm³

Formula:

d = m/v

d = density

m = mass

v = volume

by putting values,

19.32 g/cm³ = m/ 0.77 cm³

m = 19.32 g/cm³ × 0.77 cm³

m = 14.876 g

Which is the most likely to be reduced?
NISA [10]

Answer : The correct option is, Zn^{2+}

Explanation :

  • Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.

Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.

  • Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.

Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.

According to the electrochemical series, Zn^{2+} most likely to be reduced because

Hence, the ion most likely to be reduced is Zn^{2+}.

How does adding a non-volatile solute to a pure solvent affect the boiling point of the pure solvent?
belka [17]
The correct answer is the second statement. The solvent will have a higher boiling point. Adding a non-volatile solute to a pure solvent will increase the boiling point of the solvent. This solution exhibit colligative properties. Colligative properties depend on the amount of solute dissolved in a solvent. These set of properties do not depend on the type of species present.
